Modular light fixture with power pack and radiative, conductive, and convective cooling

A power pack for a light fixture comprising:

• a power pack cover, wherein an outer surface of the power pack cover comprises an emissive coating such that heat generated by a ballast is emitted from the power pack cover;
• and
• the ballast mounted in direct contact with the power pack cover;
• a power input connector mounted to the ballast and adapted to electrically connect to a power cord;
• and
• a ballast output connector mounted to the ballast and adapted to electrically connect to a lampholder connector.

A method of dispersing heat from a light fixture comprising:

• mounting a ballast in direct contact with a power pack cover such that heat generated by the ballast is conducted from the ballast to the power pack cover, wherein the ballast includes a power input connector adapted to electrically connect to a power cord and a ballast output connector adapted to electrically connect to a lampholder connector;
• applying an emissive coating to an outer surface of the power pack cover;
• and
• mounting the power pack cover to a light fixture.

A light fixture comprising:

• a lampholder electrically connected to a lampholder connector;
• a power pack comprising
• a ballast, wherein the ballast includes a power input connector adapted to electrically connect to a power cord and a ballast output connector adapted to electrically connect to the lampholder connector;
• and
• a power pack cover extending over the ballast;
• and
• a raceway mounted to the power pack cover and the lampholder, and comprising an aperture such that heat generated by the ballast is dispersed through the aperture.

A light fixture comprising:

• a light reflecting sheet, wherein an upper surface of the light reflecting sheet forms a valley;
• a lampholder mounted to a raceway, wherein the lampholder is electrically connected to a lampholder connector;
• a power pack mounted over at least a portion of the valley and comprising
• a ballast, wherein the ballast includes a power input connector adapted to electrically connect to a power cord and a ballast output connector adapted to electrically connect to the lampholder connector;
• and
• a power pack cover extending over the ballast;
• and
• a cover plate mounted adjacent to an end of the valley, wherein the cover plate comprises an aperture such that heat generated by the ballast is dispersed through the aperture.

A method of dispersing heat from a light fixture comprising:

• mounting a power pack over at least a portion of a valley formed by an upper surface of a light reflecting sheet, wherein the power pack comprises
• a power pack cover;
• and
• a ballast mounted to the power pack cover, wherein the ballast includes a power input connector adapted to electrically connect to a power cord and a ballast output connector adapted to electrically connect to a lampholder connector;
• mounting a first cover plate adjacent to a first end of the valley, wherein the first cover plate comprises a first aperture;
• and
• mounting a second cover plate adjacent to a second end of the valley, wherein the second cover plate comprises a second aperture such that air which flows through the first aperture and the second aperture disperses heat generated by the ballast.
